	*  b) Converters that deal with YUV 4:2:2, or 4:2:0 formats may also require
	*     rectangle parameters (x,y,dx,dy) to be multiple of 2. Failure to provide
	*     aligned rectangles will result in partially converted image.
	*  c) Currently only scale factors of 1:1 and 2:1 are supported; if the rates
	*     dest_dx/src_dx & dest_dy/src_dy are neither 1, or 2, the converters
	*     will fail.
